this experiment was conducted to study the effect of dietary n-3 to n-6 ratio on performance, immune response, blood parameters and fatty acids profile of broiler chickens. a total number of 192 one day old broiler chicks were randomly alloctted into 6 groups. chicks of groups 1, 2, 3, 4, 5 and 6 were fed balanced corn-soybean diets containing n-3 to n-6 ratios of 1:1, 1:3, 1:5, 1:7, 1:9 and 1:...
Morphological traits genetically correlated with wood production have been targeted as an alternative to the indirect selection of Poplar trees for high biomass production. So in this study two Populus species (P. nigra and P. alba) growing in Kermanshah, Zanjan and Esfahan provinces were selected to investigate the relationship between various leaf morphological traits and growth character...
abstract previous studies on willingness to communicate (wtc) have shown the influence of many individual or situational factors on students’ tendency to engage in classroom communication, in which wtc has been viewed either at the trait-level or situational level. however, due to the complexity of the notion of willingness to communicate, the present study suggests that these two strands are ...
Relationships between functional traits and average or potential demographic rates have provided insight into the functional constraints and trade-offs underlying life-history strategies of tropical tree species. We have extended this framework by decomposing growth rates of -130 000 trees of 171 Neotropical tree species into intrinsic growth and the response of growth to light and size. We rel...
We report the genetic relationship between growth and bone quality traits in a random mating broiler control population. Traits studied were growth rates from week 0 to 4 [body weight gain (BWG) 0 to 4], from week 0 to 6 (BWG 0 to 6), and residual feed intake (RFI) from week 5 to 6 (RFI 5 to 6). Bone quality traits were obtained at 6 weeks of age. These traits were shank weight (SW), shank leng...
Identification of easily measured physiological traits contributing to yield under specified environmental conditions would benefit genotypic selection for grain sorghum. A field experiment was conducted to determine broad-sense heritability and expected genetic advance, and to examine the relationships of grain yield with 11 physiological traits related to developmental periods, vegetative gro...
The misty ( m) coat color mutation is commonly maintained in linkage disequilibrium with the obesity mutation diabetes ( Leprdb ) to serve as a marker for Leprdb genotype. Comparisons among Leprdb genotypes are made under the untested assumption that m has no effects on traits under investigation. We tested this assumption in a population segregating m in the absence of db. Analysis of growth c...
In order to study the effects of salinity on germination, vegetative growth and some physiological characteristics of canola cultivars, two experiments were conducted at Research Station of Agricultural College of University of Kerman in 2004. The experimental design was a Completely Randomized Block with four replications. Treatments comprised all combinations of different levels of three fact...
